AIR CONDITIONER

WIPO Patent Application WO/2022/018831

A1

This air conditioner connects to a direct-current power supply connected to a plurality of systems provided in parallel, and is disposed in a first system among the plurality of systems, the air conditioner comprising: a first load which consumes power; a first capacitor which is connected in parallel to the first load and stores power to be supplied to the first load during a power failure of the direct-current power supply; a first inductor which is connected in series to a first positive electrode current path connecting a positive electrode side of the direct-current power supply and the first load, and which suppresses inrush current occurring during a power supply voltage rise of the direct-current power supply; a first diode which is connected in reverse parallel to the first inductor, and which causes a reflux of current flowing due to a counter electromotive force generated by the first inductor; and a second diode which is connected in reverse parallel to the first capacitor, and which bypasses a portion of the current flowing toward the first system due to a counter electromotive force generated by a second inductor provided to a second system differing from the first system among the plurality of systems.
